### 488. Heap, D (53)

Heap is Contentsquare's product analytics service, which captures web and mobile interactions automatically. Its server-side HTTP API accepts custom events, identities, user and account properties, and user deletion requests. Heap's server-side API suits an agent that records events. Limits are published, bulk calls take 1,000 items and track accepts an idempotency key. The API returns no analytics, and ingest calls carry no secret beyond the environment ID. Heap's help centre lists a Heap MCP article, which a bot check stopped us reading, so the MCP server is ungraded.

## How we test this category

One fixed event set loaded into each listing, then the same questions asked through its API or MCP server (a funnel conversion, a retention curve, a cohort size and an experiment result). We check the answers against known values and the limits on queries. In this run listings are graded from public evidence against the published checklist. This test hasn't run yet, so Task success is pending and the grades here come from the categories assessed from public evidence.
